Purpose
(Optional) Sets the maximum time that LSP packets remain
in the router database without being refreshed. The range is
from 1 to 65535 seconds. The default is 1200 seconds (20
minutes). After the specified time interval, the LSP packet is
deleted.
(Optional) Sets the IS-IS LSP generation throttling timers:
• lsp-max-wait—the maximum interval (in seconds)
between two consecutive occurrences of an LSP being
generated. The range is 1 to 120, the default is 5.
• lsp-initial-wait—the initial LSP generation delay (in
milliseconds). The range is 1 to 10000; the default is 50.
• lsp-second-wait—the hold time between the first and
second LSP generation (in milliseconds). The range is
1 to 10000; the default is 5000.
(Optional) Sets IS-IS shortest path first (SPF) throttling timers.
• spf-max-wait—the maximum interval between
consecutive SFPs (in seconds). The range is 1 to 120,
the default is 10.
• spf-initial-wait—the initial SFP calculation after a
topology change (in milliseconds). The range is 1 to
10000; the default is 5500.
• spf-second-wait—the holdtime between the first and
second SFP calculation (in milliseconds). The range is
1 to 10000; the default is 5500.
(Optional) Sets IS-IS partial route computation (PRC)
throttling timers.
• prc-max-wait—the maximum interval (in seconds)
between two consecutive PRC calculations. The range
is 1 to 120; the default is 5.
• prc-initial-wait—the initial PRC calculation delay (in
milliseconds) after a topology change. The range is 1 to
10,000; the default is 2000.
• prc-second-wait—the hold time between the first and
second PRC calculation (in milliseconds). The range is
1 to 10,000; the default is 5000.
